Title: Electrostatic motor
Inventor: KASANO FUMIHIRO
IPC: H02N1/00
Filed: 1993-04-15
Abstract: PURPOSE:To provide an electrostatic motor which can produce a large torque by utilizing a repulsion force in addition to an electrostatic attracting force. CONSTITUTION:The adjacent electrettes 4... of a rotor 1 are electrified so as to have polarities opposite to each other. Two electrodes 5 face the electrette 4 on the rotation direction side of the adjacent electrettes 4. If the polarity of one of the two electrodes 5 on the back side of the rotation direction is reversed, a repulsiontforce against the facing electrode 5 whose polarity is reversed is produced in the electrette 4. On the other hand, an electrostatic attracting force is applied to the electrode 5 which faces the electrette 4 on the side opposite to the rotation direction of the adjacent electrettes 4. Therefore, by switching the polarities of the respective electrodes 5 of a stator 2, a large torque is applied to a rotor 1 by the electrostatic attracting force and the repulsion force and the rotor 1 is made to rotate.

Title: Electrostatic radiant type electronic gun
Inventor: FUKUHARA SATORU
IPC: H01J37/073
Filed: 1978-07-21
Abstract: PURPOSE: To easily change from low-energy electric beam to high-energy electric beam and vice versa while keeping the radiant beam constant, by allowing to externally vary the position of a cathode or control guid in a vacuum atmosphere.  
     CONSTITUTION: An electric beam 19, radiated from a cathode 11 and passed through an anode 13, is focused by an electric lens 16 and irradiated upon a test material. These elements are all in a vacuum container 18. The cathode 11 and a control guid 12 are isolated each other by the insulator 21 and connected to an insulated power source through a high voltage cable. A d-c power source 15 and a switch 14 are disposed within the insulated power source. The switching action by the switch 14 causes the control guid 12 to be at the same potential either as the cathode 11 or as the ground. This simple arrangement enables easy switching operations between the low and the high-energy electric beams, and simplifies the operation.

Title: Motor driving equipment
Inventor: KUDO MASAHITO
IPC: H02P8/32
Filed: 1994-04-26
Abstract: PURPOSE:To prevent the structural resonance as well as natural oscillation by driving a motor so that intervals between changes of a driving speed of the motor may be gradually larger in correspondence with pulse intervals of a generated pulse pattern. CONSTITUTION:When a controlling signal is input into a controlling section 10, the controlling section 10 generates a speed command to a pulse generating section 11. The pulse generating section 11 calculates the number of driving pulses based on the input speed command and reads out a pulse pattern corresponding to the number of the driving pulses and generates a pulse pattern with the driving pulse being carried on and then outputs the pulse pattern to a motor driving section 13. The motor driving section 13 generates driving current of a motor corresponding to the input pulse pattern and outputs the current to the stepping motor 12. Then, the stepping motor 12 is so driven that intervals between changes of the driving speed may be gradually larger in accordance with the pulse intervals of the pulse pattern. The stepping motor 12 is controlled to a desired operating condition with a motor angle corresponding to dynamic characteristics.

Abstract: PURPOSE:To stabilize the performance of image formation even at the change of a refractive index of a base by setting up the center intensity of a spot of a condenser lens so as to be maximum when the refractive index of a transparent protection base for a recording medium is included within a specific range. CONSTITUTION:Light beams radiated from a semiconductor laser 1 are passed through a beam splitter 2 and form its image on the surface 6 of the recording medium having the transparent protection plate 5 as a fine spot 7 by the condenser lens 3 to record or reproduce information. At the time of reproducing, the reflected beams from the surface 6 are reflected by the beam splitter 2, photoelectrically converted by a detector 8 and amplified by an amplifier 9 to obtain a required information signal 10. When the refractive index of the base 5 is changed within the range of + or -DELTAN around N0, the condenser lens is set up so as to obtain the spot with the maximum intensity on the side having the refractive index lower than the N0. Even if plural kinds of recording media having bases with different refractive indexes are used, stable performance of image formation can be secured.

Abstract: PURPOSE:To improve throughput by providing a method for adhering a gimbal and a core slider in production of the magnetic head in such a manner that sufficient strength of adhesion is obtd. in a short period of time. CONSTITUTION:A thermosetting type adhesive 3 is used for adhering the gimbal 1 and the core slider 2 and the adhering part of the gimbal 1 and the core slider 2 is irradiated with a laser beam, by which the thermosetting type adhesive 3 is cured.

As a result, the curing state of the thermosetting type adhesive 3 is stabilized. The temp. in the adhering part of the gimbal 1 and the core slider 2 is measured by a radiation thermometer 9 and the irradiation of the adhering part with the laser beam 8 is instantaneously stopped at the point of the time when the prescribed temp. is attained. An inert gas is blown to the surface of the gimbal 1 during the irradiation with the laser beam 8 to prevent the temp. rise of the gimbal 1. As a result, the discoloration of the gimbal 1 is prevented.

Title: Surface mounting of printed wiring board
IPC: H05K3/34
Filed: 1992-03-16
Abstract: PURPOSE:To make it unnecessary to bond parts to either side of a substrate using adhesive and thus reduce the number of processes by reflow-soldering a first part using first cream solder having a high melting point and subsequently reflow-soldering a second part using second cream solder having a low melting point. CONSTITUTION:First cream solder 16A is applied to pads 12 on side A of a substrate, and a first part 20A is mounted thereon by reflow soldering. Second cream solder 24A is applied to pads 14 on side B, with the melting point of the second cream solder 24A lower than that of the first 16A. Leads 28A of the second part 26A are temporarily bonded to the second cream solder 24A, and subsequently, the board is placed in a second high temperature atmosphere. The temperature is then controlled and kept at approx. 50 deg.C, for example, in order that the second cream solder 24A will be melted but the first 16A will not. This makes it unnecessary to fix parts on either side using adhesive, shortening the production process.
